Pyxis discrepancy

[RN87]

Hello everyone, I’m looking for advice.

this is the first time this has happened to me and I don’t know how to handle this situation.

I just got an email saying there was a med discrepancy regarding a narc. The report says 9/30 1615 I pulled 10mg of oxy. The count was verified at 26. And it’s shown that I administered it to the patient at 1618. Next, another nurse comes in to pull 5mg oxy and the count is off by one. The count should have been 23, but the nurse who came in after me counted 22. Then the charge nurse came in and settled the discrepancy as a miscount, but according to the report that missing oxy was never added back to the Pyxis so it technically is not a miscount.

I did not drop one or take an extra.
 

And it’s very odd that I saw both the charge and the nurse and had multiple conversations with them through the remainder of the shift, all casual and friendly, but no one brought up that an oxy was missing. No one mentioned anything or brought up anything to my attention or asked me questions. I had no idea that the count was off until the next day, on my day off I just happened to check my work email and saw an email stating there was a discrepancy found by the pharmacy on 10/1. 
 

Has this happened to anyone? This is so confusing to me. I’m a new grad and was taken off orientation early due to lack of staff. I’ve been working there for 2 months and I’m not sure who to ask since my old preceptor is on vacation. Any advice would be greatly appreciated.
